Description
本發明係關於一種發光二極體封裝結構，特別是關於一種發白光的發光二極體封裝結構及發光二極體裝置。 The present invention relates to a light emitting diode packaging structure, and more particularly to a white light emitting diode packaging structure and a light emitting diode device.
目前一般的白光發光二極體的製造技術已相當成熟，且逐漸應用於各種發光裝置，以取代傳統的白熾燈泡及日光燈管，成為高亮度又節能的白光光源。這種白光發光二極體大致上係由藍光發光二極體晶片及螢光膠層所組成。 At present, the general manufacturing technology of white light-emitting diodes is quite mature, and it is gradually applied to various light-emitting devices to replace traditional incandescent bulbs and fluorescent tubes, and to become high-brightness and energy-saving white light sources. This white light emitting diode is roughly composed of a blue light emitting diode wafer and a fluorescent glue layer.
在螢光膠層中，發綠光的螢光顆粒及發紅光的螢光顆粒均勻的分散於透明膠材中。當藍光發光二極體晶片發出藍光時，發綠光的螢光顆粒及發紅光的螢光顆粒均會吸收藍光波段的能量，進而分別轉換激發出綠光及紅光。由於從螢光膠層所透出的光線包含紅光、綠光及藍光，且係由一點光源發射出來，因此紅光、綠光及藍光可混色形成白光。 In the fluorescent adhesive layer, green fluorescent particles and red fluorescent particles are uniformly dispersed in the transparent adhesive material. When the blue light-emitting diode chip emits blue light, both the green-emitting fluorescent particles and the red-emitting fluorescent particles will absorb the energy of the blue light band, and then convert and excite the green light and the red light, respectively. Since the light emitted from the fluorescent adhesive layer includes red, green, and blue light, and is emitted by a point light source, red, green, and blue light can be mixed to form white light.
然而，當發綠光的螢光顆粒及發紅光的螢光顆粒混合分散於透明膠材中時，由於發綠光的螢光顆粒及發紅光的螢光顆粒的顆粒特性不同(例如：粒徑大小、顆粒密度 及顆粒形狀等)，進而產生發綠光的螢光顆粒及發紅光的螢光顆粒之間的交互吸收效應，且此交互吸收效應已顯著影響了一般白光發光二極體的發光效率及製程的複雜度。據此，目前亟需一種新穎的發光結構，以解決傳統白光發光二極體所面臨的問題。 However, when the green-emitting fluorescent particles and the red-emitting fluorescent particles are mixed and dispersed in a transparent plastic material, the particle characteristics of the green-emitting fluorescent particles and the red-emitting fluorescent particles are different (for example: Particle size, particle density And particle shape, etc.), which in turn produces a cross-absorbing effect between green-emitting fluorescent particles and red-emitting fluorescent particles, and this cross-absorbing effect has significantly affected the luminous efficiency and manufacturing process of general white light-emitting diodes. Complexity. According to this, a novel light emitting structure is urgently needed to solve the problems faced by the traditional white light emitting diode.
有鑑於現有技術所面臨的問題，本發明揭露一種新穎的發光結構，及具有發光結構的燈具與背光模組。發光結構係將發綠光的螢光材料層及發紅光的螢光材料層依序覆蓋於藍光光源的出光面上。由於本發明所提供發綠光的螢光材料層及發紅光的螢光材料層係各自獨立設置於發光結構中，因此可避免傳統結構所產生的發綠光的螢光顆粒及發紅光的螢光顆粒之間的交互吸收效應。另一方面，由於本發明所提供發綠光的螢光材料層係吸收藍光激發綠光，且發紅光的螢光材料層係吸收綠光發出紅光，因此不會產生重複吸收相同波段色光的再吸收效應。 In view of the problems faced by the prior art, the present invention discloses a novel light emitting structure, and a lamp and a backlight module having the light emitting structure. The light emitting structure sequentially covers the green light emitting material layer and the red light emitting material layer on the light emitting surface of the blue light source. Because the green-emitting fluorescent material layer and the red-emitting fluorescent material layer provided by the present invention are independently provided in the light-emitting structure, the green-emitting fluorescent particles and red light generated by the conventional structure can be avoided. Cross-absorbing effect between fluorescent particles. On the other hand, since the green-emitting fluorescent material layer provided by the present invention absorbs blue light to excite green light, and the red-emitting fluorescent material layer absorbs green light to emit red light, it does not repeatedly absorb color light of the same band Reabsorption effect.
